Abstract

The utility model discloses a safe and energy-saving charger. The safe and energy-saving charger comprises a charging circuit, wherein the safe and energy-saving charger further comprises a power interruption control circuit and a current detection circuit; an output end of the charging circuit is connected with the current detection circuit; the power interruption control circuit comprises a first power interruption switch and a second power interruption switch; the first power interruption switch is electrically connected with a power supply input end of the charging circuit; the second power interruption switch is electrically connected between the output end of the charging circuit and the current detection circuit; and the current detection circuit is respectively electrically connected with the charging circuit, the first power interruption circuit and the second power interruption switch. The safe and energy-saving charger, disclosed by the utility model, has a novel design; and when an electric energy needed by a battery detected by the current detection circuit is saturated, the first power interruption switch and the second power interruption switch can cut off the circuit sequentially from the input end and the output end of the charging circuit to efficient prevent overcharge and over-discharge phenomena and realize the safe and energy-saving purpose.

Description

The energy-saving safe charger

Technical field

The utility model relates to a kind of charger, relates in particular to a kind of energy-saving safe charger.

Background technology

In the prior art, electrical bike charger can convert civil power to the required electric energy of battery vehicle, but existing charger construction is simple, function is also in simply, when the required electric energy of battery vehicle reaches capacity, can not carry out auto-breaking, so just can not reach the purpose of energy-saving safe.

Summary of the invention

For the problem that above-mentioned prior art exists, the utility model provides a kind of energy-saving safe charger.

To achieve these goals, the technical solution adopted in the utility model is: a kind of energy-saving safe charger, comprise charging circuit, also comprise power-off control circuit and current detection circuit, the output of charging circuit links to each other with current detection circuit, power-off control circuit comprises the first cut-off switch and the second cut-off switch, the first cut-off switch is electrically connected on the electrical input that supplies of charging circuit, the second cut-off switch is electrically connected between the output and current detection circuit of charging circuit, current detection circuit respectively with charging circuit, the first cut-off switch and the second cut-off switch are electrically connected.

Compared with prior art, the utility model has the advantage of: modern design, when current detection circuit detects the required electric energy of battery and reaches capacity, the first cut-off switch and the second cut-off switch can be successively from input and the output open circuit of charging circuit, effectively prevent from overcharging, electric discharge phenomena occur, and reach the purpose of energy-saving safe.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As a kind of execution mode of the present utility model, consult Fig. 1, the utility model comprises charging circuit, also comprise power-off control circuit and current detection circuit, the output of charging circuit links to each other with current detection circuit, power-off control circuit comprises the first cut-off switch and the second cut-off switch, the first cut-off switch is electrically connected on the electrical input that supplies of charging circuit, the second cut-off switch is electrically connected between the output and current detection circuit of charging circuit, and current detection circuit is electrically connected with charging circuit, the first cut-off switch and the second cut-off switch respectively.

When people use, power input is attaching plug, the access commercial power socket, the storage battery that the interlock circuit of charging circuit and battery vehicle electrically connects as battery vehicle charges normal, when charging circuit reaches abundant when saturated to storage battery charging, when current detection circuit detects required electric energy and reaches capacity, prevent from overcharging the generation of phenomenon, current detection circuit can detect this saturation condition, and notify power-off control circuit to distinguish successively open circuit from power input and output, reach the purpose of energy-saving safe.Power-off control circuit comprises the first cut-off switch and the second cut-off switch, the first cut-off switch is electrically connected on the electrical input that supplies of charging circuit, the second cut-off switch is electrically connected between the output and current detection circuit of charging circuit, its specific works principle is: tend towards stability behind the state when current detection circuit at first detects current situation for electrical input, the first cut-off switch is started working, to thoroughly disconnect for electrical input and charging circuit, played and prevented from overcharging, the purpose of energy efficient, meanwhile, the second cut-off switch is also started working, disconnect the connection of the output of charging circuit, played the safety protection function that prevents battery drain.

Pass through like this acting in conjunction of the first cut-off switch and the second cut-off switch, can directly satisfy in the prior art when the required electric energy of storage battery reaches capacity, can not carry out the function of auto-breaking, can not only play the effect of energy efficient, can also prevent that long-time charging from causing loss to storage battery and charger, this brings great convenience for people's use.

Although be recognized as a most practical and preferred embodiment and described the utility model in conjunction with current, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
